Mathematical Script Small B 𝒷

Visual Description: This character is a slender, looping lowercase b with a cursive, calligraphic feel. It has a rounded bowl and a long tail that sweeps to the right. The stroke is smooth, and the letter tilts slightly, matching other script letters in math typography. Its appearance helps distinguish it from bold or italic Latin letters.

Meaning & Usage: In mathematics and notation, a script small b is used to designate a variable, a quantity, or a special object in formulas. It signals a softer or more decorative role than plain letters, often paired with other script symbols in equations.

Historical Background: The use of script letters grew with typographic styles that emphasize variables and objects in math. Early typesetting adopted ornate scripts; later, digital fonts offered parity with standard letters. The idea stayed simple: style can signal meaning without changing the math itself.

Practical Use: In math editors and calculators, you may insert a script small b to emphasize a variable or object in a formula. Quick UI controls let you switch font styles, apply scripts, or compare expressions, using the same interface you use for other operations.
